No Safety Data Sheet on file.
CarCareTruth has not received a Safety Data Sheet from the manufacturer for this product, so no GHS hazard classification can be cited. The tiers below are cautious defaults — “Beyond SDS” — translated from the product’s ingredient chemistry and how comparable formulations classify, not from a manufacturer hazard classification. Request an SDS from the manufacturer before use.

Only when: when spraying
Translated from the ingredient chemistry
No H319 or H318 confirmed (SDS unavailable). Aerosol mist of light hydrocarbons and ketone solvents at face level during engine-bay work is the exposure trigger. Chemistry analysis of heptane and acetone is consistent with mild transient eye irritation on direct aerosol contact.
No Safety Data Sheet is on file for this product. The tier above is a cautious default translated from the ingredient chemistry, not a cited manufacturer classification. Request an SDS from the manufacturer before use.
Only when: prolonged use
Translated from the ingredient chemistry
No H315 confirmed (SDS unavailable). H315 (skin irritation) is not in the confirmed H-code array. Label-visible solvents (heptane, acetone) are defatting agents on prolonged contact but do not carry confirmed skin-irritation classification at mixture level. Brief incidental contact during a typical TB cleaning session is the realistic scenario.
No Safety Data Sheet is on file for this product. The tier above is a cautious default translated from the ingredient chemistry, not a cited manufacturer classification. Request an SDS from the manufacturer before use.
Translated from the ingredient chemistry
No SDS signal word confirmed. Label chemistry (heptane, acetone aerosol into engine bay) presents an inhalation hazard consistent with the aerosol-into-confined-space exposure scenario. Light hydrocarbon and ketone vapors can cause drowsiness and dizziness in poorly ventilated spaces. Use outdoors or with the hood up and garage door open.

No PPE specified in published sources for ventilation. Absence does not imply “not needed” — no Safety Data Sheet is on file, so request one from the manufacturer before use.
PPE tiers here are cautious defaults translated from the product’s ingredient chemistry — no manufacturer SDS is on file to cite. Not professional safety advice. How we report safety.
Scope of these PPE tiers. The tiers on this page translate the product's Safety Data Sheet where one is published, plus its ingredient chemistry, into a comparable rating. They describe a formulation, not a situation: a tier is not a safety determination for any specific user, task, quantity, or environment. The manufacturer's label and use instructions govern how the product is handled. Where the product is used at work, the employer's PPE program and hazard assessment under 29 CFR 1910.132 decide what protection is selected, not this page.

TL;DR Light-hydrocarbon blend for air intake and throttle body cleaning · fast-evaporating chemistry and a 360-degree nozzle. The back label has no explicit O2-sensor-safe or catalytic-converter-safe claim; "Safe for all component surfaces" is not a substitute. The SDS portal is down, so health scores reflect the no-SDS floor (Health 5.0/10 · NO SDS). Community evidence is too thin to rate above average (too few owner reports and no forum data). Use outdoors or with the hood up.
Remove the air intake duct, hold the throttle plate open, spray into the bore (5-15 seconds), and wipe with a microfiber. The light-solvent chemistry is consistent with fast, residue-free evaporation, but without review text or forum evidence there is no community record of before/after results or sensor-code reports for this product.
A reasonable choice for a port-injected throttle body if you already run Mag1 products. Skip it if explicit O2/cat-safe chemistry is required · the label makes no such claim and the SDS is not available to verify it. Skip it for GDI engines: aerosol TB cleaner cannot reach intake-valve carbon deposits; a dedicated GDI cleaner or walnut-blast is the right tool.
SDS unavailable · PPE tiers inferred from label ingredient chemistry only. Heptane and acetone aerosol in an engine bay can cause drowsiness; lungs-recommended PPE is the chemistry-inferred minimum. Eye protection advisable. The CARB compliance claim is a regulatory-accounting result (acetone is an exempt solvent) · absolute solvent emissions are still high. No Prop 65 warning on label. Petroleum-origin solvents are not biodegradable.
CarCareTruth scores Mag1 Air Intake/Throttle Body Cleaner at 5.1 out of 10 on the composite CCT score, with a health sub-score of 5.0/10. The CCT score blends real-world effectiveness, ingredient health impact pulled from the manufacturer's safety sheet, and environmental footprint against a published category rubric. See the methodology link on this page for the full scoring breakdown.
Per the Safety Data Sheet ingredient disclosure: Back-of-bottle label (mag1.com product page image, 2026-05-19): Heptane (CAS 142-82-5), Acetone (CAS 67-64-1), Propane (propellant, CAS 74-98-6). No additional ingredients legible. No aromatic hydrocarbons (toluene, xylene, benzene) visible. SDS §3 full ingredient list not available.
